You know, when they decide on a landing site for the new rover, the JPLnews youtube channel should post that video as a video-response to this video. That would be cool to see after watching this video, which by the way, is utterly fascinating.
I'm not from JPL but I think I have the answer. Spirit and Opportunity were built specifically as low cost rovers as part of a program at NASA to send cheap Orbiters/ rovers to other celestial bodies.
The Mars Science Laboratory is not part of this program. To give you a cost break down, spirit and opporunity each cost a couple hundred million to make. The MSL on the other hand will end up costing a couple BILLION. Building a second of these may just be too expensive for NASA's budget.
Good point. Besides, the rover is gonna get stuck on a rock or something eventually (as happened recently). So it might aswell get stuck somewhere interesting.
Speaking of getting stuck, cant they have some helium balloon or similar to inflate from a pod on the back of the rover and lift it out of being stuck?
Seems a shame to waste that helium that got vented from the lander they dropped at the north pole. That's if they use helium on the rovers.
I'd like to see some mountains in the pictures that come back from Mars. Viking, Sojourner, Spirit and Opportunity all have very 'flat' surroundings. I know it's more safe for those probes to land in such areas... but some mountains on the horizons would be a nice change in the photos sent back from Mars.
They chose Gale Crater! Yayyy!

@Noogymonster I meant, the helium could inflate an airbag beneath the rover to free the sunken wheels from the soil. Then the airbag would deflate.

@TableWolfMusic How would the helium stop from making the rover float all together.

Its a hamfisted idea but an idea nonetheless.

This video is also on Nasa videogallery
Final candidate landing sites and reasons are:
North
Mawrth Vallis -Diverse mineral signatures -Mixing of soils by impacts and water
South
Holden Crater -Indicates water flowed from valley into crater lake, overflowing, leaving layers
Eberswalde Crater -Water obviously flowed out of highlands into crater
Equator
Gale Crater -Once filled with water Many minerals exist ie Sulplates Sediments Clay
I hope it's Gale. Once equator was warmer? Likelier life.
